many screamed 'let me down' as they nervously made their way up the climbing wall at the YMCA King's Park Centenary Centre in Jordan on Sunday.
But after a few tries many of the participants in the Coca Cola Adventures Day were hooked and couldn't wait to get back up.
The event was organised by Swire Coca-Cola Hong Kong and the YMCA and was supported by Young Post.
Like most of the participants, it was Wong Shuk-kwan's first taste of the extreme sport.
'I've never had the chance to try this sport before. It's pretty difficult,' said the 15-year-old.
'It's scary when you are high up on the wall and you cannot figure out the next step to take. But it's a lot of fun and it's challenging.'
Another beginner, Chow Mei-nam, 15, said: 'It's something new to me. It is really challenging.'
